These convert pressure into voltage. When certain crystals are compressed or stretched, they exhibit a voltage across their faces, which can be utilised for various applications. The simplest example is an inexpensive 'crystal' phonocartridge: when the attached stylus vibrates in the grooves of a record, the crystal creates variations in voltage which can be amplified using an amplifier which then produces sound via a loudspeaker.
These crystals also work the other way around, compressing or expanding when voltages are applied across their faces. This is the principle behind, for example, ultrasonic cleaners -high-frequency voltages applied across the crystal results in ultrasonic vibrations.

What does an ultrasound scanner consist of?
the transducer and the data processing unit. The transducer both produces the sound waves that penetrate the body and receives the reflected echoes. Transducers are built around piezoelectric ceramic chips.
Can the energy converted by peizo electric transducers be stored?
Yes. A piezoelectric transducer converts stress (pressure) into electrical energy. You can store electricity in a battery or capacitor.
What is the basic circuit of transducer?
The question here has been framed wrongly. There is nothing like a general circuit for a transducer. Depending on a transducer you may have many circuits. For eg. a Piezoelectric crystal is a transducer, it can convert both ways; mechanical vibrations to electrical and electrical to mechanical. So you see, there is nothing like a general circuit for a transducer. Another better example would include an Antenna which converts electro-magnetic waves into a electric signal. All that you can say at max is that a transducer is a device that converts one form of energy to another. And that is either due to the virtue of the property of a material or due to a certain circuitry which will vary from transducer to transducer.
How can we convert sound to electricity efficiently?
One way to efficiently convert sound to electricity is by using a device called a piezoelectric transducer. This device can convert sound waves into electrical energy by utilizing the piezoelectric effect, where certain materials generate an electric charge when subjected to mechanical stress. By placing the transducer in an area with high sound intensity, such as near a loudspeaker or in a noisy environment, it can efficiently generate electricity from the sound waves.
How do you make a device that projects a sonic wave?
To create a device that projects a sonic wave, you can use a transducer, such as a piezoelectric speaker or ultrasonic transducer, which converts electrical signals into sound waves. Connect the transducer to an audio source or a signal generator to produce the desired frequency. Encase the transducer in a suitable housing to direct the sound waves effectively. Ensure proper power supply and circuitry to amplify the signal for sufficient projection range.
Name the device that converts non electrical quantity to an electrical signal?
-- microphone -- piezoelectric crystal -- dynamo
How can you use piezoelectric transducer practically to measure pressure or weight of human?
Piezoelectric transducers can be utilized to measure pressure or weight by converting mechanical stress into an electrical charge. When a human stands on a piezoelectric sensor, the pressure applied generates a voltage proportional to the weight. This voltage can then be measured and calibrated to provide a direct weight reading. Such sensors are often employed in scales or pressure-sensitive mats for applications in health monitoring and fitness tracking.
Why is quartz used in piezoelectric transducer?
Quartz is used in piezoelectric transducers because of potential for high voltage input and acoustic power. Quartz is a piezoelectric crystal and when it is mechanically strained or deformed by stress, electric charges appear on some surfaces. When the strain is reversed, the polarity of the charges reverse. This allows vibration of quartz crystals to be transformed into electric pulses.
